Energy stores and transfers Task 1: Energy stores Draw a line to match the energy store to its description. Energy store Description kinetic stored in foods, fuels or batteries chemical involves splitting or fusing atoms elastic potential stored in moving objects thermal stored in objects off the ground nuclear stored as heat gravitational potential stored in stretched objects Task 2: Energy transfers Complete the questions below. a) Identify the energy transfer taking place in the following scenarios: i) A person picking up an object. ii) A cup of tea warming up a person’s hands. iii) A toaster using infrared waves to toast some bread. b) Give an example of an electrical energy transfer. Name __________________________ Science Energy stores and transfers Task 3: Identifying energy pathways Draw energy pathway diagrams for the following scenarios: a) A long distance runner transferring energy from their muscles into movement. b) An apple falling from the top of a tree. c) A pair of wet socks drying on a radiator.
